Some Recommendations:

"David is an extremely capable engineer. He has great
ideas, and the implementation skills to quickly put them into
practice."

- Brett C., Technical Director @ Transmeta

"Code and (good!) ideas flow from David like water from a spring.
A top-notch technical talent in coding and CPU verification (and a
jillion side projects that speak for themselves), when given the
latitude to show off his stuff, he'll deliver way beyond what you
thought possible."

- Andrew A., Sr Logic Design Engineer @ SandCraft

"The fact that Dave is cool, smart and great guy to
work with, is not as much interesting as, the fact that he gets the
job (freaky complex verification kind of a job) done on-time even
when we have been in severe shortage of time and resources."
